Abstract A program control plate directly actuates power switches. The program control card is a plastic plate or card which has a pair of racks along the bottom side edges and a plurality of ridges on top. The plate or card is inserted in a reader device which has gears which engage the racks. The card is motor driven by control pulses to drive the control card under a bank of microswitches which are actuated by the ridges on the card. The gear arrangement has an initial locating stop which engages the racks in a zero reference position. After the sequence of operations, or at any time, when the card is withdrawn, it actuates a switching arrangement which drives the gears to the zero reference position so that when the card is again inserted, the stop will be in the proper position.
Program control means adapted to directly control power devices comprising: a control plate; means in said plate for indexing said control plate linearly along a predetermined axis; a plurality of ridges mounted on said plate, each ridge being located on a line parallel to said axis, said ridges and lines being spaced predetermined amounts from each other means for sensing the removal of a plate from said frame, and means responsive to said sensing means to set said motor-driven gears to zero reference position, corresponding to said plate reference position.
